Orlando (CNN) - The duct tape found on Caylee Anthony's skull could have been sufficient to kill the little girl, prosecutors said Friday.
The state showed jurors a graphic new video, which presented pictures of Caylee's skull superimposed over her smiling face. It demonstrated the duct tape could conceivably cover both the girl's nose and mouth, suffocating her as prosecutors allege.
"I believe that the exhibit was necessary to establish the state's theory that this duct tape was sufficient to be the murder weapon," said attorney Jeff Ashton.
The defense had argued vigorously against allowing the video into court, saying it presented just one of many possible scenarios and would serve only to inflame sentiments among the jurors.
But Orange County Chief Judge Belvin Perry agreed to allow the video into evidence. Determining the role of duct tape in the girl's death was "highly relevant," he said.
Perry also denied a mistrial motion made by the defense, related to the video, at the close of Friday's proceedings.
Caylee's mother, Casey Anthony, 25, faces seven counts in her daughter's death, including first-degree murder, aggravated child abuse and misleading investigators. If convicted, she could face the death penalty.
Earlier Friday, the chief medical examiner in the case said the way in which prosecutors say Caylee's body was discarded left no doubt that the girl was intentionally killed.
Dr. Jan Garvaglia testified that Anthony's failure to report her daughter missing for more than a month was just one of three red flags that strongly indicate foul play.
The others were the discovery of the girl's remains amidst black garbage bags in a wooded field - "tossed in a bag to rot" was her testimony - and the presence of duct tape on the girl's skull.
"There is no child that should have duct tape on its face when it dies," Garvaglia testified. "There is no reason to put duct tape on the face after it dies."
Attorneys for Anthony have said Caylee was not killed, but rather drowned in the family pool and that Casey Anthony and her father, George Anthony, panicked and tried to cover up the death. George Anthony denied that scenario during his testimony.
Prosecutors allege Anthony used chloroform on her daughter and suffocated her by putting duct tape over the little girl's mouth and nose. They allege she put her daughter's body in her car trunk before disposing of it. Caylee's skeletal remains were found on December 11, 2008, less than a mile from the home of Anthony's parents.
Anthony has pleaded not guilty and denied having anything to do with her daughter's death.FULL STORY
